The operational sequence of the cassette pickup is as follows:
1. The DC controller rotates the drum motor when it receives a print command from the formatter.
2. The feed roller rotates.
3. The cassette pickup solenoid is driven at a specified timing.
4. The cassette pickup roller rotates and picks up the top paper
5. The cassette separation roller removes any multiple-fed sheets.
6. One sheet of paper is fed into the product.

Cassette media-size detection and cassette-presence detection

The DC controller determines the size of the paper loaded in the cassette and also whether the cassette
is installed to the product by monitoring the cassette media width switch and the cassette media end
switch.
The cassette media width switch and the cassette media end switch contain three sub-switches each.
The DC controller detects the size of paper and the presence of cassette according to the combination
of the switches and notifies the formatter.
